I wanted to easily make HTTP requests (both GET & POST) with a simple interface that returns promises.
The popular request & request-promises package are good, but I wanted to figure out how to do it w/out using external dependencies.
The key features are:
| function iframeURLChange(iframe, callback) { | |
| var lastDispatched = null; | |
| var dispatchChange = function () { | |
| var newHref = iframe.contentWindow.location.href; | |
| if (newHref !== lastDispatched) { | |
| callback(newHref); | |
| lastDispatched = newHref; | |
| } |
